Gratuitous pretty picture
15th February 2008
The wierdest example of this aspect of atmospheric physics I experienced was seeing heat haze shimmering up from the snowpack with snow drifting around my feet and an air temperature of +7 degrees C. (Cairngorm in March 1998). Convection, conduction, radiation: heat and snow make quite a conundrum.
Well, with more cloud forecast (but staying dry and cool) those South facing slopes are likely to be a little firmer during the day.
